Unit 4: Definitions Horizontal cabling: The cabling between and including the outlets and the horizontal cross-connect. Backbone cabling: The cabling that connects between telecommunications rooms and equipment rooms. Patch cords: Any flexible piece of cable that connects one network device to the main cable run or to a patch panel. Connectors: A device attached to the end of a cable‚ receiver‚ or light source that joins to another cable or device. Conduit: A rigid or flexible metallic or nonmetallic

various layers Note: Shielding protects transmitted data by absorbing stray electronic signals‚ called noise‚ so that they do not get onto the cable and distort the data. Coaxial cable is more resistant to interference and attenuation than twisted-pair cabling. Attenuation is the loss of signal strength that begins to occur as the signal travels farther along a copper cable. [pic] Types of Coaxial Cable There are two types of coaxial cable: ⢠Thin (thinnet) cable ⢠Thick (thicknet) cable Which

bus (Oliviero and Woodward‚ 2009‚ p. 104). Bus topology is the choice in most LAN topologies. A bus topology is a type of network setup where each computer and network device is connected to a single cable or backbone that typically uses coaxial cabling. The signal travels both ways from one end of the bus to the other. A terminator is needed at both ends of the bus so the signal does not reflect back across the bus or so it does not bounce back and forth across the cable. When data is sent

Purpose: (a) The purpose of the “CS/EE Lab Building RFP” is to provide a functional specification for a comprehensive technology network system‚ including required network cabling and components and required network devices. The purpose of this is also to provide adequate details and criteria for the design of this technology network system. (b) The contractor shall provide cables‚ network equipment‚ and components necessary

other with a high speed connection. Recommendation: Install Category 6 UTP 1000Base T Ethernet Cabling. While this may not be the most cost effective solution‚ it will alleviate all of the customers concerns by providing a high speed connection that can handle the voice over I.P. system as well as connect all network switches and reduce the current bottlenecks experienced by the customer. This cabling solution will also allow the network to run at full duplex rather than the current half duplex.

What is an Electrician? An electrician can be defined as a person who installs and maintains electrical systems‚ communications and lighting control systems. These systems can be in businesses‚ schools‚ factories‚ commercial buildings‚ homes and in large equipment. In almost every project‚ the electrician is responsible for getting the electricity from its source and distributing it to the various parts. The electrician job might sound simple‚ but it is not. To achieve electrician duties without

Ghattas The differences between LED and Laser Transmitters LED LED (Light-Emitting Diode) is a two-lead semiconductor light source. It resembles a basic p-n junction diode (is a boundary or interface between two types of semiconductor material‚ p-type and n-type‚ inside a single crystal of semiconductor.‚ which emits light when activated.

usually a hub or a switch. Each connected device has a dedicated‚ point-to-point connection between the device and the hub. The star network topology is by far the most widely implemented topology in use today. Star topology networks require more cabling than bus‚ but the tradeoff comes in the form of a more solid network topology. A break in the network media will only affect a single node‚ since every node has a dedicated connection to the central device; a hub or switch. This also makes the central
